What to Expect

Your Rochester to Phoenix flight is quite a journey across the country, exposing you to a variety of weather patterns that can cause turbulence. Shortly after takeoff, you might encounter some minor mechanical turbulence over the Northern Appalachians as the wind interacts with the mountains. As you cross the Great Lakes, be prepared for possible lake-effect turbulence, especially if the air temperature is much colder than the water. Further west, over the Ohio and Mississippi Valleys, frontal and convective turbulence are possible, depending on weather systems. Then, as you head over the Great Plains, expect some clear-air turbulence, or CAT. In Tornado Alley, anticipate potentially severe convective turbulence, especially during storm season. As you approach Phoenix, the Southern Rockies can create mountain wave turbulence. Finally, the Mojave and Sonoran Deserts can cause some thermal turbulence. Pilots are well-versed in navigating these conditions, and turbulence is a normal part of flying, not a sign of danger.

The Rochester to Phoenix route passes over the Southern Rockies in New Mexico and southern Colorado. While somewhat lower than the peaks to the north, these mountains still produce notable mountain wave turbulence, particularly when strong southwesterly winds aloft align perpendicular to the ridgeline.

Turbulence Factors on This Route

• Mechanical Turbulence: The Northern Appalachians generate low-level mechanical turbulence during strong post-frontal northwest winds.
• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Frontal Turbulence: The Ohio Valley is a preferred storm track where frontal boundaries and embedded convection create turbulence year-round.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.

When Is This Route Bumpiest?

The smoothest flights between Rochester and Phoenix tend to be in summer, early fall, fall, and winter. During these months, the weather patterns are generally more stable over the Great Plains and Rockies, reducing the likelihood of clear-air, convective, and mountain wave turbulence. Winter, late fall, early winter, spring, early summer, early spring, and late winter can be bumpier due to stronger jet streams (increasing CAT), increased convective activity in the Mississippi and Ohio Valleys, and more pronounced mountain wave effects as you approach the Rockies. The differences in air temperature create stronger lake effect turbulence over the Great Lakes as well.

Tips for This Flight

For the calmest possible flight, consider booking a morning departure, as this is often before daytime heating creates as much thermal and convective activity in the deserts. Any turbulence you experience on this route will likely feel like driving on a slightly bumpy road, or a series of short, sharp jolts. To help you stay relaxed, choose a seat over the wing for greater stability, stay well-hydrated, and practice deep, slow breathing; remember, the pilots are constantly monitoring the weather and are trained to handle these conditions safely.
